A heat flux passes through a gas from a ...

A heat flux passes through a gas from a heated plate with a temperature `T_1` to a cold plate with a temperature `T_2` . The linear dimensions of the plates are large compared to the distance between them. Is the temperature gradient the same along the entire heat flux? Why when measuring the thermal conductivity coefficient must we place the plates horizontally, with the plate with the higher temperature placed above the one with the lower temperature?
